“…Further, acetate-grown Aerobavter showed a heightened activity on succinate, fumarate, malate, oxalacetate, and pyruvate, but not on a-ketoglutarate, cis-aconitate, or citrate. Similar results were obtained with E. coli (Ajl, 1950;Ajl and Kamen, 1951). The suggestion was put forth (Ajl and Wong, 1951), therefore, that A. aerogenes, when grown on acetic acid, may oxidize the C~-fatty acid in a manner similar to that of E. coll.…”
